American Johnson minimally invasive hemorrhoid surgery (PPH), also known as anastomotic hemorrhoidal mucosal cricothyrotomy, is based on the anal cushion theory, the use of anastomotic treatment of circumferential prolapsed hemorrhoids new technology. Johnson & Johnson Medical Devices Limited, in cooperation with Dr. Antoniolongo, successfully developed a hemorrhoidal anastomosis in 1993, which is specially designed for the treatment of severe hemorrhoids of degree II-IV, without destroying the normal physiological function of the anal cushion, and significantly shortening the operation time and greatly reducing the post-operative pain. It is through the rectal mucosa and submucosal tissue for circular excision. It effectively treats severe prolapsed internal hemorrhoids. It can also be used for the treatment of rectal mucosal prolapse, rectal mucosal condyloma, rectal proptosis, etc., which brings convenience to patients. Compared with traditional surgery, it has the following advantages: 1, safety: no need to remove the anal cushion, maximize the preservation of the normal function of the anus, to avoid anal stenosis, anal incontinence and other complications. 2.Little pain: pull back the hemorrhoids prolapsed from the anus to their original position, and at the same time cut off the blood vessels providing blood to the hemorrhoids, with little damage to the perianal skin, so there is almost no pain after the operation. 3.Small trauma, fast recovery: anastomosis annular excision of mucosa is a non-open wound, less bleeding, fast recovery, can quickly return to normal life. Therefore, for patients suffering from the above diseases, this procedure can be taken as the first choice of treatment.
